To all whom it may concern:

Be it known that I, GLnMnivr -LEE Dow- .vnr, a citizen of the United States, residing at Cmcinnatn 1n the county/of Hamilton and State of- Ohio, have invented certain new and useful Improvements in Type-Writer Attachments, of which the following is a specification.

My invention broadly relates to a means automatically actuated by atype-writer to indicate on the writing sheet the variations in the spacing.

My invention more particularly relates to an attachment to .a type-writer having the general construction, function and objects of the device shown in my former patent No. 698,469, granted April ing attachment fortype-writers.

notch, indentation. embossing or other I have only shown so much of the machine in the present drawings as will serve to illustrate the purpose and the operation of my new attachment.

This machine is designed to print a series of addresses upon a long transcript sheet, which is then taken to a machine where impressions are taken from the printing. The

transcript sheet is fed from a supply roll to the action of the type-writer and wound upon a receiving roll.

I have found that the variation in spacing inherent in friction feeds is such as to render it practically impossible to duplicate upon the impression machine the spacing or intermitting feed of the transcript sheet through the typewriter, and it is the purpose of this invention to provide an attachment for the type-writer which will be automatically actuated by the carriage movement to make a physical impression upon the transcript sheet; which impression will serve in cooperation with the mechanism of the impression machine, to duplicate the spacing of the transcript sheet in the type writer. As illustrated this physical impression is a punched hole, though it may be a phys ical change wrought in the transcript sheet.

The various features of the invention will be more fully set forth in the description of the accompanying drawings, making a part of this specification, in which I Figure l is a rear elevation.

the lower end of said lever has an adjustable screw 12 adapted to be brought against an abutment or the frame of the machine when the carriage is shifted to travel whereby the punch is actuated. The transcript sheet passes between said punch members just before it engages the platen roll. By these means the transcript sheet is punched whenever the carriage engages the lever 11 against the frame.
